Acute Toxicity
Result
Does not cause acute toxicity
Oral / inhalation / dermal
Irritation / corrosion
Skin / eye/ respiratory tract
Sensitisation
Toxicity after repeated exposure
Oral / inhalation / dermal
Skin contact causes irritation.
Eye contact causes irritation.
May be irritating for respiratory tract.
May cause an allergic skin reaction.
Does not cause toxicity to internal organs after repeated
exposure in animal studies by oral route.
Similar materials did not cause toxicity to internal
organs after repeated exposure in animal studies by
dermal route.
Genotoxicity / Mutagenicity
Based on the available test data, not expected to cause
genetic effects.
Carcinogenicity
No data is available.
Toxicity for reproduction
Does not cause effects on the reproduction or on the
foetal development in animal studies.
6.
Environmental Effects
In contact with water, HDDA will hydrolyse slowly. However HDDA is readily biodegradable.
As HDDA is readily biodegradable in water, it is assumed that HDDA is also biodegradable in
soil and sediment and thus can be considered as non persisting in soil and sediment.
After evaporation or exposure to the air, the product will be rapidly degraded by
photochemical processes.

Adsorption to solid soil phase is not expected.
Effect Assessment
Aquatic Toxicity
Result
Toxic to aquatic organisms.
Fate and behaviour
Result
Biodegradation
Readily biodegradable.
Bioaccumulation potential
Significant accumulation in organisms is not to be
expected.
PBT / vPvB conclusion
This substance is not considered to be persistent,
bioaccumulative nor toxic (PBT). This substance is not
considered to be very persistent nor very bioaccumulative
(vPvB).
7.
Exposure
7.1
Human health
Consumer exposure:
Since the consumer is not exposed directly to the unreacted monomer of HDDA, an exposure
to the consumer is negligible.
Worker:
Exposure can occur either in an HDDA manufacturing facility or in the various industrial
facilities that use HDDA. Those working with HDDA in industrial operations could be exposed
during maintenance, sampling, testing, or other procedures. Each industrial facility should
have a thorough training program for employees and appropriate work processes and safety
equipment in place to limit unnecessary exposure. Safety showers and eye-wash stations
should be accessible nearby. Workers should follow the safety measures recommended in
the Extended Safety Data Sheet (eSDS).
7.2
Environment
HDDA is readily biodegradable and will therefore be degraded rapidly within the waste water
treatment process. Based on this information and on additional hazard data, the substance is
not regarded to pose an unacceptable risk for the environment. All uses of HDDA are
considered to be safe for the environment.
8.
Risk Management recommendations
Human health measures
Eye/Face protection
Safety glasses with side-shields
Skin protection
Long sleeved clothing
Hand protection
Gloves: nitrile rubber > 0,5 mm,(suitable gloves tested to
EN374). Replace gloves immediately when torn or any
change in appearance (dimension, colour, flexibility, etc) is
noticed
Respiratory protection
When using concentrated chemicals always make sure that
there is adequate ventilation.
Organizational measures
Ensure workers are duly trained to minimize exposure

3/5
Engineering control
Apply technical measures to comply with the occupational
exposure limits
When working in confined spaces (tanks, containers, etc.),
ensure that there is a supply of air suitable for breathing and
wear the recommended equipment
Environment protective measures
Do not allow material to contaminate ground water system.
All effluent releases that may include the substance must be directed to a (municipal) waste
water treatment plant that removes the substance from the final releases to the receiving
water.

Regulatory Information / Classification and Labelling
9.1
Regulatory Information
This substance has been registered under:
 EU Regulation EC 1907/2006 (REACH)
9.2
Classification and labelling
Under GHS substances are classified according to their physical, health, and environmental
hazards. The hazards are communicated via specific labels and the e-SDS. GHS attempts to
standardize hazard communication so that the intended audience (workers, consumers,
transport workers, and emergency responders) can better understand the hazards of the
chemicals in use. Substances registered for REACH are classified according CLP (EC)
1272/2008, implementation of the GHS in the European Union.
Classification
According to REGULATION (EC) no 1272/2008, the pure substance is classified:
 Skin Corrosion/Irritation; Category 2.
 Serious Eye Damage/Eye Irritation; Category 2.
 Skin Sensitization; Category 1.

 GHS07: Exclamation mark
Hazard statement
 H315 – Causes skin irritation
 H317 – May cause an allergic skin reaction
 H319 - Causes serious eye irritation
Alternative classification according to Globally Harmonized System (GHS)
 H313 – May be harmful in contact with skin
 H315 – Causes skin irritation
 H317 – May cause an allergic skin reaction
 H319 – Causes serious eye irritation
 H401 – Toxic to aquatic life
